Semester 1 Physics Final

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in kilometers per hour (km/hr) or meters per second (m/s).

Front

How do you convert meters to feet?

Back

To convert meters to feet, multiply the number of meters by 3.281.

Front

What is instantaneous velocity?

Back

Instantaneous velocity is the velocity of an object at a specific moment in time, represented as the slope of the position-time graph at that point.

Front

What is average acceleration?

Back

Average acceleration is the change in velocity divided by the time over which the change occurs, typically measured in meters per second squared (m/s²).

Front

How do you calculate the time it takes for an object to fall from a height?

Back

Use the formula: t = √(2h/g), where h is the height in meters and g is the acceleration due to gravity (approximately 9.81 m/s²).

Front

What is the formula for speed?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What does a position-time graph represent?

Back

A position-time graph shows the position of an object over time, allowing us to determine its speed and direction of motion.

Front

What does a velocity-time graph represent?

Back

A velocity-time graph shows the velocity of an object over time, allowing us to determine its acceleration.

Front

How do you find the slope of a graph?

Back

The slope of a graph is found by dividing the change in the y-axis by the change in the x-axis (rise/run).
